Use 3.14 for pi.
Round answer to nearest penny.

Answers

3.14 • 1.2^2•4

= $397.9
Answer : $1.2 per cubic foot

Explanation :
1. Do your radius to the power of two and multiply by pi (3.14)
2. That would be 4.5216 you then multiply that by 4(your height) and get about 18
3.You divide 22(cost of oil) by 18(drum of oil) and get about $1.2 per cubic foot

Please help me explain as well. AD is 48. I will give brainliest.

Answers

Answer:

The area of the rectangle is 48

Step-by-step explanation:

We know that AE is 6 and ED is 8, since it forms a triangle, use the Pythagorean theorem to find AD, which is one side of the rectangle.

The Pythagorean theorem says that a^2 + b^2 = c^2.

a is AE, b is ED, and c is AD, so 6^2 + 8^2 = c^2, 36 + 64 = c^2, 100 = c^2, 10 = c, so AD is 10

The area of the triangle is half of AE times ED, so 1/2(6)(8) = 1/2(48) = 24, the area of the triangle is 24.

Since the area of a triangle is 1/2 of the base times the height, we can figure out the height:

A = 1/2bh, 24 = 1/2(10)h, 24 = 5h, 4.8 = h, so the height of the triangle (and rectangle) is 4.8.

The height of the triangle is also the height of the rectangle:

The area of the rectangle is 4.8*10 = 48

Jayden brought $38.75 to the state fair. He bought a burger, souvenir, and a pass. The burger was 1/4 as much as the souvenir. The souvenir was 2/3 the cost of the pass. Jayden had $3.00 leftover. What is the cost of each of the 3 things?


I need the answer right now please no link

Answers

Answer:3.25 burger, 13.00 souvenir, 19.50 pass.

Step-by-step explanation:

1:4:6 is the ratio “1/4 of the”  souvenir aka 1:4. “The souvenir is two thirds” 4 is 2/3   3/3=6    hence 1:4:6

38.75-3 for the actual amount of money spent is 35.75 divided by 11 for one unit is 3.25

so for the burger 1x3.25=3.25. for the souvenir 4x3.25=13. And for the pass 6x3.25=19.5

A worker can load 4 pallets in 30 minutes. At that rate, how many pallets can he load in 4 hours?

Answers

8 pallets each hour so it would be 8 x 4 to find the answer. the answer is 32 pallets

Answer:

32

Step-by-step explanation:

1 hour = 60 minutes

Thus, 30 minutes if half an hour.

The worker can load 4 pallets every 30 minutes.

30*2=60

4*2=8

So the worker can load 8 pallets every 60 minutes, or every hour.

8*4=32

So, a worker can load 32 pallets in 4 hours.

BONUS: The worker can load 1 pallet every 7.5 minute

This graph shows a proportional relationship, y=kx. What is the constant of proportionality, k?

Answers

The answer is k = 7
Have a great day

The constant of proportionality, k is equal to 7.

What is proportionality?

The term proportionality describes any relationship that is always in the same ratio.

Given that, a graph shows a proportional relationship y = kx, is in the form of equation of a line, y = mx + c, where, m is the slope, so we can say that, the k here is the slope.

Slope = y₂-y₁ / x₂-x₁

= 35-21 / 5-3

= 14 / 2

= 7

Since, the slope of the line is 7 therefore, k = 7.

Hence the constant of proportionality, k is equal to 7.
